+1 maintenance report

[Sergio Durigan Junior]

This week has been my +1 maintenance shift.  I had some interruptions
here and there during the week, but here's what I did:

* Retriggers

I didn't do many retriggers over the week; I preferred to focus on
investigating and solving bugs.  Here are the successful retriggers I
did (there are a few unsuccessful ones that I'm not listing here).

* Investigation

** ruby-libxml

- https://bugs.launchpad.net/ubuntu/+source/ruby-libxml/+bug/1942130

A bunch of failures due to some libxml2 upstream changes.  I fixed them
all and also forwarded whatever was necessary to upstream.

** thin

- https://code.launchpad.net/~sergiodj/ubuntu/+source/thin/+git/thin/+merge/407931

this is the oldest blocked package on update_excuses.  I found the
problem and submitted an MP for the Ubuntu package as well as a PR for
upstream, but we decided to wait to hear what upstream thinks about the
proposal before going ahead and uploading.  I will wait until next week,
and if there's no feedback from upstream I will revive the MP.

** mpich

- https://bugs.launchpad.net/ubuntu/+source/mpich/+bug/1942265

Problem with GCC-11/GFortran.  Uploaded fix to Ubuntu and also forwarded
the patch to the Debian package.

** docker.io & glibc

- https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1942276 & https://github.com/tianon/debian-docker/pull/12
- https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1942276

This one was interesting.  I was able to reproduce the issue locally,
and after some investigation it became clear that the issue was not on
docker.io itself.  Eventually, we found that this was actually a glibc
bug at play.  I've added the glibc component to the bug and started an
attempt to investigate what was actually going on.  I felt I was on the
right track, but mwhudson beat me to it and came up with a fix that was
later approved & uploaded.

** golang-github-go-resty-resty: https://bugs.launchpad.net/ubuntu/+source/golang-github-go-resty-resty/+bug/1942491
** golang-github-google-martian: https://bugs.launchpad.net/ubuntu/+source/golang-github-google-martian/+bug/1942639

These two packages have been blocking golang-golang-x-net from migrating
for 103 days.  I investigated and tracked down the problem: both
packages were being affected by proxy issues.  After some though on how
to best deal with this, I decided to hack their d/rules, override
dh_auto_test and unset $http_proxy (anything else would involve patches
and more complex things).  Aside from workarounding the problem, the
other positive outcome here was to set up a local container with squid
in order to reproduce these dreaded proxy failures (instead of resorting
to building packages on a PPA and then running autopkgtest there).

Thanks,
